Research
My research is in the area of artificial intelligence, and includes contributions in the areas of artificial intelligence and education, computational linguistics, spoken language, and user modeling. My work has included both fundamental research and applied research resulting in technology transfer and patents. My most recent research has primarily focused on Natural Language Technology for Educational Applications. Current projects include:
- (CourseMIRROR) Developing and Optimizing Reflection-Informed STEM Learning and Instruction by Integrating Learning Technologies with Natural Language Processing
- (eRevise+RF) An Automated Writing Evaluation System to Support Text-Based Argumentation and Revision
- (InspireWrite) Recognizing and Amplifying Student Ideas in First-Year College Writing
Brief Biography
I am the School of Computing and Information's Associate Dean for Mentoring Development, Professor of Computer Science (CS), a Senior Scientist with the Learning Research and Development Center (LRDC), and Faculty of the Intelligent Systems Program (ISP), all at the University of Pittsburgh. CS and ISP are part of Pitt's School of Computing and Information (SCI). I moved here from the Garden State (aka New Jersey), where from 1985-2001 I was a member of the Artificial Intelligence Principles Research Department, AT&T Labs - Research (formerly Bell Laboratories); From 1990-1992, I was also an Assistant Professor of Computer Science at Columbia University. I received my Ph.D. and M.S. in Computer Science from the University of Rochester, and my A.B. in Mathematics and Computer Science from the College of William and Mary in Virginia. Here are my informal and more formal (but outdated) versions of my academic geneology.
